Congenital Trigger Thumb
What is it?
Trigger thumb typically occurs in infancy. It is characterized by a flexed thumb and a small nodule on the palm side of the thumb. It is this nodule that makes it difficult to straighten the finger or thumb. While triggering can occur in any finger, in children it is most likely to occur in the thumb.
Unlike adults, children generally do not have any pain. Instead you will see that your child's thumb is staying in a flexed or bent position.
Your physician may recommend splinting. In some cases the trigger thumb will resolve without any intervention. If there is no improvement after 12 months of age, your physician will likely recommend surgery to release the tendon that is causing the thumb to stay in the bent position. After surgery your childs hand will be bandaged. Your child may also be wearing as splint to keep the thumb stable and more comfortable. The stitches will be removed in about 2 weeks.
